Market order

What is Market order in forex and CFD trading

A Market order is an instruction to a broker or trading platform to immediately buy or sell a specified quantity of a financial instrument at the best available price at that moment in the market. It is used when a trader prioritizes instantaneous execution over a specific price, making it critical for reacting quickly to unexpected news or sudden price movements. A trader confirms a Market order by selecting the ‘Buy by Market’ or ‘Sell by Market’ option and seeing the position immediately appear in the Trade or Terminal window of the trading platform. The executed price of a Market order is known only after the order is filled, which can lead to slippage during periods of high volatility or low liquidity.

Key facts about Market order

• Execution Priority: Prioritizes Speed of Execution (Time) over Price Certainty.
• Price Mechanism: Executes at the best current Bid Price (for a Sell order) or Ask Price (for a Buy order).
• Slippage Risk: A Market order carries the highest risk of Slippage, where the executed price differs from the quoted price due to latency and fast price movement.
• Order Fill Guarantee: Provides a high guarantee of Order Fill for the specified size, provided there is sufficient liquidity at or near the current price.
• Platform Type: Implemented as Instant Execution or Market Execution, depending on the broker’s model; Market Execution is standard for ECN/STP brokers.
• Cost Impact: The immediate cost is the Spread Cost applied at the execution price; Slippage can increase the entry cost.

How Market order works in forex and CFD trading

The process of executing a Market order involves the broker instantly matching the trader’s request with the available liquidity in the Order Book.

The process involves these steps:

1. Trader Initiation: The trader selects the instrument (e.g., EUR/USD) and specifies the Position Size (Volume) on the platform’s order ticket, then clicks ‘Buy by Market’ or ‘Sell by Market’.
2. Order Routing: The trading platform instantly sends the Market order request to the broker’s Execution Server.
3. Liquidity Sweep: The Execution Server immediately checks the best available Bid or Ask price in the aggregated Liquidity Pool (Order Book).
4. Order Fill: The Order is filled against the best available price(s) until the full requested Position Size is matched. If the Volume is large, it may be filled at multiple prices (Partial Fills).
5. Confirmation and Open: The executed price(s) are sent back to the trading platform, and the new position appears in the trader’s account with a realized execution price.

Example of Market order with a real trade

A trader sees a sudden breakout and wants to immediately buy EUR/USD regardless of a minor price fluctuation.

Result: The trade is opened instantly at 1.10015, with zero commission. The Slippage results in a higher initial drawdown of $14.00 compared to the quoted price, but no per-trade commission fees.

How Market order affects your cost and risk

The primary effect of a Market order on Cost and Risk stems from its inherent vulnerability to Slippage. While it guarantees Execution, the final price may be worse than anticipated, increasing the initial drawdown and potentially exceeding the calculated Risk per trade.

Market order compared with related concepts

A Market order guarantees Execution at the best available price but not a specific price, while a Limit order guarantees Execution at the specified price or better, but not necessarily Execution itself, if the market never reaches that level.

Market order vs. Stop order

A Market order is an instruction for immediate action, triggering instantly when placed, whereas a Stop order is a Pending Order that only converts into a Market order when the market price first touches the designated Stop Price.

Broker differences in Market order across the industry

The key distinction lies in whether the broker acts as a Counterparty (Market Maker) or a Facilitator (ECN/STP Broker) in Market order execution, which directly affects Slippage exposure.

How to verify Market order on your trading platform

A Market order is verified simply by the speed and price of the execution, as it is a one-step action. The process is consistent across platforms like MT4 and TraderEvolution.

1. Open New Order Ticket: Right-click on the instrument chart and select New Order, or use F9.
2. Select Order Type: Ensure the Type is set to ‘Market Execution’ or ‘Instant Execution’, not Pending Order.
3. Enter Volume: Specify the desired Position Size in the Volume field (e.g., 0.5 Lot).
4. Click Execute: Click the ‘Buy by Market’ or ‘Sell by Market’ button immediately.
5. Check Terminal Window: Navigate to the Trade or Terminal window and check the Open Price of the new position.
6. Compare Price: Compare the Executed Open Price with the Ask or Bid price quoted on the chart just before clicking, noting any Slippage.
7. Sanity check: The executed Open Price should be very close to the quoted Bid or Ask price, with any difference indicating Slippage.
